3 Claims. 1

This invention relates to inoculation devices, and more particularly toinoculation devices for animals employing the so-calied "scratch method,

A main object of the invention is to provide a novel and improvedvaccination device which is very simple in construction, easy to use andreliable in operation.

A further object of the invention is to provide an improved vaccinationdevice which is inexpensive to manufacture, sturdy in construction andeconomical in its use of vaccine materials employed for inoculation.

Further objects and advantages of the invention will become apparentfrom the following description and claims, and from the accompanyingdrawings, wherein:

Figure 1 is an elevational view of a vaccination device constructed inaccordance with the present invention.

Figure 2 is an enlarged vertical cross-sectional detail view takenthrough the lower portion of the inoculation device of Figure 1.

Figure 3 is an enlarged perspective view of a brush tip member employedwith the vaccination device of Figure 1,

Figure 4 is an enlarged horizontal cross-sectional view taken on line4-4 of Figure 2.

Figure 5 is an enlarged vertical cross-sectional detail viewillustrating an alternative form of the invention.

Referring to the drawings, ll designates an elongated rod which isemployed as the handle of the vaccination device. Secured in the endportion of handle rod II is a needle member l2 projecting substantiallyaxially from the end of the rod. The end portion of rod H is somewhattapered and secured thereon is a sleeve member l3 formed at its lowerportion with an axial bore through which the needle l2 passes. Securedto the end of sleeve member [3 is a tip member l4 also axially bored forthe passage of said needle. Tip member I4 carries a tuft of brushbristlesv I5 which terminate substantially flush with the sharp tip ofneedle l2.

Instead of employing a tip member H the sleeve member I 3 may behollowed out at its lower portion and the tuft of brush bristles secureddirectly in the hollowed-out portion, as shown in Figure 5.

In operation, the operator clips the brush end l5 of the device into thevaccine receptacle and merely scratches the skin of the animal orsubject by drawing the brush end of the device across the skin. Thevaccine is smeared across the 2 scratch by the brush bristles I5 duringthis process and thereby completes the inoculation. It is impossible tomiss the scratch because the brush bristles carrying the vaccineautomatically follow the scratching needle tip.

The brush bristles are made preferably short so as to absorb only asmall amount of vaccine. The instrument is therefore economical in theuse of vaccine as well as positive in its inoculating action.

While certain specific embodiments of a vaccination device have beendisclosed in the foregoing description, it will be understood thatvarious modifications within the spirit of the invention may occur tothose skilled in the art. Therefore, it is intended that no limitationsbe placed on the invention other than as defined by the scope of theappended claims.

What is claimed is:

1. A vaccinating device comprising a tubular body member having astepped bore definin a relatively large diameter upper bore portion anda relatively small diameter lower bore portion opening through the lowerend of said body member, said bore portions defining a stop shouldertherebetween, a brush secured to the lower end of said body member, anda handle member having a lower end portion removably insertible in thelarge diameter portion of said body member and a needle projectingaxially from the lower end of said handle member to extend through saidsmaller diameter bore portion of said body member, said lower endportion being insertible into the bore of said body member so as toengage the lower end thereof with said stop shoulder whereby the degreeof projection of said needle below the lower end of said body member ispositively limited to a position within said brush.

2. A vaccinating device comprisin a tubular body member having a steppedbore defining a relatively large diameter upper bore portion and arelatively small diameter lower bore portion opening through the lowerend of said body member, said bore portions defining a stop shouldertherebetween, a brush secured to the lower end of said body member, anda handle member having a lower end portion removably insertible in thelarge diameter portion of said body member and a needle projectingaxially from the lower end of said handle member to extend through saidsmaller diameter bore portion of said body member, said lower endportion being insertible into the bore of said body member so as toengage the lower end thereof with said stop shoulder whereby the degreeof projection of said needle 3 below the lower end of said body memberis positively limited to a position within said brush, said brushcomprising a cap positioned on the lower end of said body member.

3. A vaccinating device comprising a tubular body member having astepped bore defining a relatively large diameter upper bore portion anda relatively small diameter lower bore portion opening through the lowerend of said body member, said bore portions defining a stop shoullertherebetween, a brush secured to the lower end of said body member, anda handle member having a lower end portion removably insertible in thelarge diameter portion of said body member and a needle projectingaxially from the lower end of said handle member to extend through saidsmaller diameter bore portion of said body member, said lower endportion being insertible into the bore of said bod member so as toengage the lower end thereof with said stop shoulder whereby the degreeof projection of said needle below the lower end of said body member ispositively limited to a position within said brush, said brushcomprising a bunch of bristles securably inserted in a socket providedin the lower end of said body member.
